The organic carbon concentration of Lake Superior is discussed in terms of a simple mathematical model that treats the lake as a well mixed basin. Major sources, outflows, and biochemically mediated removal of organic carbon are analyzed in the time frame of yearly average values. Data on organic carbon concentrations of watershed drainage, rainfall, anthropogenic inflows and contributions from photosynthetic production are analyzed as are the removal of organics by biochemical oxidation and sedimentation. The long range projected effects of the major sources and sinks on the yearly average organic carbon concentration of the lake are described.
